摘要:

A deep-level tube railway with high traffic density has special requirements; also an interruption to any of the main or auxiliary services can be very serious. The present London Underground system, resulting from an amalgamation of separate undertakings, provides a tribute to the sound design and workmanship of the early equipment

摘要:

The variable-reluctance or switched-reluctance motor has some remarkable characteristics that make it attractive for dozens of applications. With CAD software now available, and many prototypes established, there should be few technicalbarriers between the laboratory and a number of successful niches in the drives market

摘要:

The complexity of modern turbogenerator plant and instrumentation, and reduction in manning levels, means that instrumentation and monitoring equipment is usually located a central control room. It is now essential for instrumentation requirements to be specified at the same time as the main plant

摘要:

Public perception of what constitutes a healthy or high-quality product is leading manufacturers to exploit alternative processes and presentation. As a result, aseptically processed foods, which are cooked prior to packaging, are appearing in the shops. This article reviews the development of a novel electrical cooking process targeted for the modern aseptic process line
